FirebaseAuth.AuthStateListener.onAuthStateChanged(mAuth) not working as expected

Currently figuring out working with Firebase Auth in Android (MVP). My flow goes something like this:

Activity > Presenter > Interactor > AuthHelper
Activity < Presenter < Interactor < AuthHelper

The Auth Helper class is the sole class that directly interacts with the FirebaseAuth instance. My question is about how the AuthStateListener works in this scenario:

• Interactor has FirebaseAuth.AuthStateListener

• Interactor initializes Auth Helper class, passing the AuthStateListener

  class MyInteractor implements FirebaseAuth.AuthStateListener {
  
      FirebaseAuth.AuthStateListener listener;
  
      public MyInteractor(){
          MyHelper myHelper = new MyHelper(this);
  
          listener = new FirebaseAuth.AuthStateListener() {
              @Override
              public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                  Log.d("TAG", "onAuthStateChanged called");
              }
          };
      }
  
      public void signOut(){
          myHelper.signOut();
      }
  }
  

• Helper passes the FirebaseAuthInstance to the listener

  class MyHelper {
  
      private static FirebaseAuth mAuth;
  
      public MyHelper(FirebaseAuth.AuthStateListener listener){
          mAuth = FirebaseAuth.getInstance();
          listener.onAuthStateChanged(mAuth);
      }
  
      public void signOut(){
          mAuth.signOut();
      }
  }
  

• myHelper.signOut() is called

Expected result:

onAuthStateChanged() in the interactor would trigger.

Received result:

onAuthStateChanged() is not triggered.

I instead tried a different approach where I passed the mAuth after calling signOut():

public void signOut(){
    mAuth.signOut();
    listener.onAuthStateChanged(mAuth);
}

This triggers the onAuthStateChanged. Am I missing something here?
